Not all Pokémon have an equal chance of appearing in Pokémon Go. Many of them leave the game, and Kyurem is one of the Legendary Pokémon that appears every now and then. You will have to beat him in five-star raids alongside other trainers if you want to catch him. When you catch him, what are the chances that you will encounter a brilliant version of Kyurem in Pokémon Go?
We can confirm that the brilliant version of Kyurem has arrived in the mobile game. Whenever you fight him and defeat him in a five-star raid, there's a chance he may eventually appear as a brilliant version. The glossy version has a low chance of appearing, but there is still a chance. When Kyurem was originally released, there wasn't a brilliant version at all.
If you want to have a chance to find a brilliant version, we recommend starting five-star raids or using Remote Raid Passes to work together with other players around the world. Kyurem is a formidable fighter, so the more coaches team up to beat him, the better he is.
Kyurem will only be available in Pokémon Go from December 16 to December 31. He will disappear in early 2022. After that, we don't know when he will return to the mobile game.
